Words I wish I wrote myself, n. 2

Reading, I had learned, was as creative a process as writing, sometimes more so. When we read of the dying rays of the setting sun or the boom and swish of the incoming tide, we should reserve as much praise for ourselves as for the author. After all, the reader is doing all the work – the writer might have died long ago.

The Emperor New Clothes

OK, it’s been a while since I wrote my last post here. I imagine I could, with a small effort, build up a whole bunch of very good reasons for that. But the truth is,  I’m too lazy to do it. And that’s exactly why I skipped these last three months here. Laziness.

Anyway, I wanted to give it another try since some time, but after such a long vacation, the post subjects that came to my mind always seemed somehow unworthy of the occasion. Well. I guess today I have no more excuses. It’s indeed well possible that, in a few years, people will ask each other what the hell they were doing in such a day. Where they were, how did they live through the event. Exactly like it did happen for 9/11. History could be a whole different story from today on. Maybe. Then, indeed, maybe not.

So, the emperor today had donned new clothes. Magnificent ones, or so it seems. In any case undeniably much, much better than the old ones (not such a difficult task, I concede). And we, from our lookout at the borders of the empire, cannot but rejoice for that. Still, there is a possibility that eventually we’ll discover the naked truth hiding behind the clothes, and won’t like it so much.

In the past, I had expressed some perplexity about Obama, but I ended up liking him more and more. True, it somewhat helped that the alternative,  possibly the only decent candidate the Republicans could put in the field, had squandered his campaign by choosing a strategy based solely upon denigration and by banding together with the genius she-hunter from Alaska.

So, today I’m quite happy. The event in itself has at least a strong, positive symbolic relevance. Therefore I push at the back of my mind the doubts I still have. But I cannot resist to mention again a quote from the late Kurt Vonnegut:

“There is a tragic flaw in our precious Constitution, and I don’t know what can be done to fix it. This is it: only nut cases want to be president.”

I’m personally quite convinced of the truth of that. One must indeed be mad to be willing to bear such  a burden.

However,  there are things (just a few simple actions, indeed) that should absolutely be done for the progress of the US and the rest of the world, but are faced by such a strong resistance that only a madman would be willing to undertake them.

Let’s hope America has just elected such a madman, unlikely as it is.

And in case you didn’t get enough…

…have a look at these wonderful photographs from The Big Picture – Boston.com. (Hat tip to Phonkmeister.) Enjoy.

P.S.: And don’t worry. This is not really going to happen (in Italian).

Everything you always wanted to know about LHC…

… but were afraid to ask.

Hat tip to Dorigo, for pointing out in his blog the video above, an LHC rap shoot on location at CERN. At least from a first view the text is way more accurate and to the point than most divulgative articles about the machine and experiments in recent newspapers (no sweat, you may say, but still…).

Information about the author here (from Dorigo’s post comments).

In case you’re still curious (and still don’t dare to ask), I’d like to mention this public information site about LHC, including an LHC blog (watch out for news) and webcams (you can even have a look at what’s going on in the Atlas control room).

A Modest Proposal

Posted in G 1 with tags , , , , on July 11, 2008 by Roberto Gravitazero

I started to suspect some time ago that in Italy there could be a problem with gypsies, or, to employ a more politically correct term, Roma people.
Not much of a news, you say? OK, right, sometimes I’m sort of slow in catching up with the current news.

However, I did a small research, and yes, I’m positive: we have a problem. Only, it’s a bit worse than I expected. The good news is that there is a solution. A rather simple one, in fact. And quite obvious. It somehow emerges naturally if only one cares to give a closer look at the issue, and it could be both effective and not too difficult to implement.

Bear with me, you won’t be disappointed. I hope. Most likely you would be surprised.

It all started last week when I come upon a mention in an article on Repubblica of a recent survey put in place by the European commission about discrimination and inequality in Europe. Repubblica reported that Italy resulted the EU country with the highest dislike for Roma. Of course, the few random percentages mentioned in the newspaper couldn’t possibly give a comprehensible view of the situation. I was intrigued however by the fact that France was mentioned as much more tolerant than Italy. I live in France, and I know that Roma are much more numerous here than in my country of origin. I resolved I would check the numbers some other time.

Well, I have found some time now, so I retrieved the original report and I looked for Rom population estimates in Wikipedia,  with the aim to check for correlations.

The survey, for the part of interest, involved two questions, put to population samples across EU countries:

1) How comfortable would you feel in having a Rom as a neighbour? (Scale from 1 tot 10, highest more comfortable.)

2) Do you have any Roma friend ?

I thus plotted the survey results against the percentage of Roma over the entire population of the different countries, and here are the results (including error bars for estimate uncertainties):

So, there is hardly any overall correlation between the number of Roma in a given country and how they are perceived. there. In Italy the Roma are only a tiny fraction of the total inhabitants (less than 0.2%), as in most of Europe, but all countries with similar low Rom densities are much more tolerant than Italy, and their score show a rather large spread. The western Europe countries with a relatively high Rom density are amongst the more tolerant, while east Europe countries, with the higher number of Roma, are slightly below average but show, interestingly enough, a positive trend (higher Rom density = high tolerance). Therefore, the claim that in Italy there is a reaction to the too high number of Roma starts to look a bit fishy. What’s so special about Italy, then? Somebody particularly malignant  could be tempted to answer that Italy is the only EU country with a prime minister with a dominant position in the mass media and a very strong interest first in creating dissatisfaction with the previous government and then in distracting the public from more important issues (for which he has no clue about possible solutions). However we should dismiss here such hypothesis  as unscientific, on the ground that it’s impossible to either prove it or disprove it in this context.

It’s however interesting to look at the plot below, dealing with the answers to the second question. of the survey It is not surprising that only four percent among Italians admit to have a Rom friend, since it’s so hard to find one at all. On the other hand, almost half of Bulgarians have friends among Roma. It looks like xenophobic reaction are damped by increased presence of minorities, thus more opportunities to meet and understand them.

Eventually, I find the last plot the more intriguing. I compare here the reaction to Rom neighbours among the countries supposedly closest to Italy for culture, social structure and standard of living. I include UK and Germany, the other larger western states, for comparison. It is very tempting to admit a trend towards higher acceptance in case of a stronger presence of Rom minorities.

The conclusion is blatantly obvious: Italians are not comfortable with Roma, because there are not enough Roma in Italy. An increase in their number would give Italians more chances to know them better and therefore be reassured.

So, if the present government really want to reduce social alarm caused by Roma people, it should first of all try to attract more of them. It may not solve completely the problem, since Italy looks like such an anomaly, but this simple study show that it can only improve it.

Unfortunately I suspect that, as is often the case for simple, logical solutions based on a scientifically sound analysis, the political power would gladly ignore such a suggestion. Pity for them us.

Angels & Demons

Posted in G 0 with tags , , , , on June 15, 2008 by Roberto Gravitazero

As many will know, Angels & Demons is a rather appalling, if highly successful, book by Dan Brown.

Director Ron Howard is presently working on the movie version of the novel, following up on his previous rendition of another bestseller by Brown, The Da Vinci Code. Tom Hanks will be starring in the movie, in the role of professor Robert Langdon, which he had covered in the previous one as well.

I learned today that the Vatican had denied access to its premises for the shooting, as it had previously done for the Da Vinci Code, on account that the movie “offends common religious feelings”.

As you may know, the novel start with a murder of a physicist taking place at CERN and the theft of an absurd amount of anti-matter in order to set-up an unlikely anti-matter bomb. The process of anti-matter production, the physics involved and the laboratory itself are also described in a rather ludicrous manner. Such that CERN felt obliged to rectify a few questions in one of its public web pages.

I was wondering if the movie plan was requiring some shooting at the CERN site, so I had a look and discovered that it was indeed so. And, guess what, not only CERN management apparently had already granted access to the site, but CERN physicists had helped to get some physics issues straight in the script.

I have still some reserve about the likely result, but this is not the main point. What is worth noticing is the different behavior of CERN and the catholic church administrators.

It could well be that in the novel the church has been treated in a worse way than science or CERN had been. Or they are more easily offended. Or less tolerant. Or again, could be that science is less vulnerable than religion to what adds up to a fair amount of essentially innocuous bullshit wrapped around a cleverly devised plot.

And could be that this has something to do with science being based on facts and logic rather than faith. Up to you to decide.

For me, I’m rather happy to be on the side of Angels, this time. Or are we the Demons?

Well, whatever.

No, in spite of the title and the picture, this is not a musical post.

I just wanted to inform you that since a few days I’m experimenting with Tumblr. Mainly in Italian. Here.

I’m not sure I’m really getting the knack of it, though. Comments welcome.
